Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter. The catheter may include a catheter shaft and a balloon. The balloon may comprise a cone portion, a waist portion, and a body portion. A fiber braid may be disposed along the balloon. An inner surface of the waist portion may be thermally bonded to an outer surface of the catheter shaft and an inner surface of the fiber braid may be adhesively bonded to an outer surface of the waist portion.
Claims20
A catheter, comprising:
- a catheter shaft;
- a balloon, the balloon comprising a cone portion, a waist portion, and a body portion;
- and
- a fiber braid disposed along at least a portion of the balloon;
- wherein an inner surface of the waist portion is thermally bonded to an outer surface of the catheter shaft and an inner surface of the fiber braid is adhesively bonded to an outer surface of the waist portion.
The catheter of claim 9, wherein the thermoset adhesive includes a moisture cure material, a UV cure material, or a combination thereof.
A catheter, comprising:
- a polymeric catheter shaft;
- a balloon having a cone portion, a waist portion, and a body portion, the balloon including a thermoplastic elastomer;
- and
- a fiber braid disposed along the balloon, the fiber braid including molecularly oriented high molecular weight polymer;
- wherein an inner surface of the waist portion is bonded to an outer surface of the polymeric catheter shaft using a first method and wherein an inner surface of the fiber braid is bonded to an outer surface of the waist portion by a second method that is different than the first method so as to preserve the molecular orientation of the molecularly oriented high molecular weight polymer of the fiber braid.
A method of making a catheter assembly, the method comprising:
- disposing a fiber braid about a balloon, the balloon comprising a cone portion, a waist portion and a body portion, the fiber braid being terminated distally at a predetermined point relative to the waist portion;
- disposing the balloon on a catheter shaft;
- applying heat to at least a portion of the waist portion to thermally bond an inner surface of the fiber braid to an outer surface of the waist portion;
- and
- adhesively bonding the inner surface of the distal portion of the fiber braid to the outer surface of the waist portion.
